good product

Did not work as expected

I used in my diy co2 kit for few weeks and it was very useful than drilling holes in bottle cap and long useless process. Highly recommended. I am now using co2 cylinder with whole kit but I have kept this for emergency purpose and for nano tank set up. Cost is high but paisa vasool if know how useful it is.

Both caps are damaged after few days

Fitting is good works as intended but guality is not that great mine broke in a month
